Interaction between Graphene Surfaces and Extracellular Polymeric Substances of Biofilms




Abstract: Many researchers and we confirmed that graphene is very sensitive to biofilm formation. Since biofilms are composed of many kinds of organic polymers and inorganic matters, they are as complicated systems. We have to clarify the components that would react with graphene and how the reactions would occur. This depends on the combinations of bacteria, production processes of graphene, experimental conditions, etc. In this study, we carried out some experiments to determine which components of biofilms would prefer to attach to graphene and how the tendency would change according to the differences among experimental conditions. We will present the experimental data so far, discuss the sensitivity of graphene for biofilms, and propose how to apply the results to practical applications in the future.
